High precision measurements of induced and transferred recoil proton polarization in d(polarized gamma, polarized p})n have been performed for photon energies of 277--357 MeV and theta_cm = 20 degrees -- 120 degrees. The measurements were motivated by a longstanding discrepancy between meson-baryon model calculations and data at higher energies. At the low energies of this experiment, theory continues to fail to reproduce the data, indicating that either something is missing in the calculations and/or there is a problem with the accuracy of the nucleon-nucleon potential being used.
Spin polarization observables of the deuteron photodisintegration at low energies are studied in a pionless effective field theory up to next-to-next-to-leading order (NNLO). The total and differential cross sections, induced neutron polarization $P_
The experiment was carried out using BINA detector at KVI in Groningen. For the first time an extensive data analysis of the data collected in back part of the detector is presented, where a clusterization method is utilized for angular and energy in
Recoil proton polarization observables were measured for both the p($vec {rm e}$,e$^primevec{rm p},$) and d($vec {rm e}$,e$^primevec{rm p},)$n reactions at two values of Q$^2$ using a newly commissioned proton Focal Plane Polarimeter at the M.I.T.-Ba
We report the first large-acceptance measurement of the beam-spin asymmetry for deuteron photodisintegration ($vec{gamma} dto pn$) in the photon energy range $400<E_{gamma}<630$~MeV. The measurement provides important new constraints on the mechanism
Precision measurements of vector and tensor analyzing powers of the $^{2}{rm H}(vec d,dp){n}$ break-up process for configurations in the vicinity of the quasi-free scattering regime with the neutron as spectator, are presented. These measurements are
